Additionally, in tissue infections, ADSCs release the antibacterial peptides and proteins, such as antibacterial peptide LL-37, hepcidin, β-defensin-2, and lipocalin-2, which inhibit the synthesis of DNA, RNA, and valid proteins in infected cells to facilitate the cell-killing process and restore the balance of infection and inflammation (160–162). The gene discussed is LCN2; the disease is infection.
